jumping_the_queue.rar - The beginning of a winter break near Spring Festival is always the beginning of a peak period of transportation. If you have ever tried to get a train ticket at that time, you must have witnessed the endless queues in front of every ticket box window. If a guy has seen his friend in a queue, then it is very much likely that this lucky guy might go straight to his friend and ask for a favor. This is called "jumping the queue". It is unfair to the rest of the people in the line, but, it is life. Your task is to write a program that simulates such a queue with people jumping in every now and then, assume that, if one in the queue has several friends asking for favors, he would arrange their requests in a queue of his own,2006-11-04 20:29:57,下载6次
